The Cometic C8406 is a high-performance Multi-Layer Steel (MLS) head gasket engineered specifically for 1993-1999 Honda CBR900RR motorcycles with a 75mm bore diameter and 0.040 inch compressed thickness. This precision-manufactured gasket delivers superior sealing performance for both stock and modified sport bike engines.

Multi-Layer Steel Construction:

• Center layer features uncoated stainless steel that can be varied to accommodate multiple thickness requirements
• Outer layers are embossed and coated on both sides with Viton rubber for maximum sealing capability
• LCE (Load Control Embossments) promote even torque load across the gasket surface, reducing bore distortion
• Enhanced piston ring seal translates to improved compression and power output
